JAMES EWING, OF NEW YORK, N. Y.

IMPROVED CLAMPS FOR WASH-BASINS.

Specification forming part of Letters Patent No. 59,572, dated Novemberl 1866.

To all whom it may concern:

Be it known that I, JAMES EWING, of the city of New York, in the countyof N ew York, in the State of New York. have invented a new and ImprovedBasin Clamp or Bracket; and I do hereby declare that the following is afull and exact description thereof', reference being had to theaccompanying' drawing, and to the letters of reference marked thereon,the dra-wing representing' a vertical central section.

The object of my invention is to secure permanentl)` the basin to thema-rble slab; and to enable others skilled in the art to make and usethe same, I will proceed to describe its construction and operation. Arepresents the marble slab; B, the basin; fj', the ilanges of the basinc, the basin clamp or bracket; d, the bolts, and e the nuts. The boltsare made with an oblong head or T shape, which are let into the underside of the slab the required distance, and secured therein by lead orcement. Between the slab and the flan ges of the basin I also usecement, the basin being put in its place while the cement is soft orplastic. The clamps c c arethen put on the bolts, and by means of thenuts c e are screwed rmly to the marble. p

My improvement in basin-clamps consists in making them out ofsheet-brass or other sheet metal, by stamping or pressing` in dies ofthe proper shape and size, then placing them, one at a time, between twodies to produce the desired eorrugations or indentations, the rim oredge being turned up nearly at right angles; or the whole can beeliected at one operation by proper appliances. By indentin g the clampand turning up the rim or edge I secure more strength than can be hadunder the ordinary cast clamp. The highest turned up portion of the rimprevents the clamp from canting or the nut t'rom being too muchtightened.

I construct my bolts out of brass wire or other metal rod, rolled ordrawn of the desired length and thickness, and by means of proper clampsor vise give to them the oblong or T- shaped head, as represented in thedrawing.

I claim- As a new article of manufacture, the clamp c', of sheet metal,stamped to receive the form, substantially as set forth, for the purposeof securing basins to marble slabs by the nut d, as specified. y

JAMES EWING.
